SPECIFICATION lforming peut of Letters Patent No. 297,357, eared April 22, 1834.

Application filed March 29, 18E3. (Model.)

'To {LZ/ whom, it mag/concern,.-

Be iti-known that L WALLACE DINGMAN, of Battle Creek, in the county of Calhoun, and in the State of Michigan, have invented certain I5 of the machine on its next round.

The object of the invention is, rst, to provide a simple, convenient, and effective Ina chinefor perfectly delivering the gavel to the binding mechanism, so that each bundle shall have the straw uniformly arranged and free from entanglement; and, secondly, to provide certain devices whereby a horizontally-traveling automatic rake running parallel to the cutter-bar and level therewith shall gather, carry laterally, and deliver the gavels to the self-binder as desired, as more fully hereinafter specified. '.lhese objects I attain by the means illustrated in the accompanying drawings, in which- Figure l represents a plan view of my device; Fig. 2, a longitudinal section; Fig. 3, a sectional View through the line y y, Fig. l; and Fig. 4, a plan view of the device with the platform, cutter-bar, and the curved guide removed and the standard shown in section.

r[he letter A indicates the frame or portion of the frame of a harvester, of the usual construction, mounted on wheels, as usual, and which is provided with the ordinary platform, B, the cutter-bar, and operating mechanism, which last forms, however, no part of the present invention and need not be shown. At one side of the platform B are located the upright standards C, in which is journaled a shaft, D, which has on one end a pinion, E, which intermeshes with a cog-segment, F, pivoted to a stud, G, and provided with a slotted extension, H, in which is located a slide, I, which is connected to a wrist-pin on a rotat- 5o ing disk, F', secured to the rotary shaft K,

which receives its motion from the drivinggear of the machine or harvester. f

At the rear end of the shaft D is secured a gear-wheel, L, intermeshing with a Y gearwheel, M,mounted on a short stud, N, secured to one of the standards, the said wheel M intermeshing with a pinion on the end of a shaft, P, which carries sprocket wheels R, over which pass the belts S, having apertures in which the sprockets engage for the purpose of actuating the beltsr- Said belts pass over sprocket-wheels T', journaled at the opposite end of the frame. The belts have suitable bearings, in which are eccentrically journaled the ends of the rale-head \V, which are pro- 65 vided with curved rake-teeth X. To the said rake-head is hinged a weighted shoe, Y, which, by coming in contact with the bottom A' when the rake movesinward, holdstheteeth in a vertical position. rlhe frame is provided with a bottom or lower platform, A', to which are secured the reversely-pointing springs B', which are adapted to engage the rake-head as it is reciprocated,as morefully hereinafter explained.

The platform B is provided with slots D', which extend from the outer side to the line of the standards before mentioned, and which correspond in number to the number of teeth on the rake head. Between the slots, on aline with the inner portion of the cutter-bar, are arranged a series of curved springs, E', which prevent the grain from scattering when it falls on the platform.

To the outer end of the bottom A'is secured the curved guide E2, to the upper part of which are attached the guards F2, between which the rake-teeth are adapted to work as they pass upward through'the slots in the-platform.

The bottom A' has near its inner end the opening G, into which the hinged shoe or triplever Y on the rake-head is adapted to fall at each reciprocation of the rakehead, to permit the latter to turn to withdraw the teeth below the platform on the return-stroke of the rake. A similar recess, G', is provided at the outer end, to permit the shoe Y to drop so as to engage the bottom A' when the rake is again moved inward.

Hinged to the bottom A' about in al line with the inner ends ofthe slots in the platform, roo

.in a horizontal position.

and between said slots, are the grain-holding cesses, in which they lie, so thatthe next rakefingers H H', which are pressed upward and held in position by suitable springs, I', as shown, which fingers are operated by the mechanism now to be described.

In the bottom A are formed suitable recesses, wherein are hinged the spring lever-arms M, which project upward, and to the upper ends are attached cords N', which pass over the rake-head, and are attached by means of suitable rings to the ngers H' H. The lower ends ofthe said levers M are formed with short arms P', which engage with the bottom ofthe recessesin which the levers are pivoted, whereby the levers and grain`holding fingers H are prevented from moving too far.

Pivoted to the finger-bar on the front part ofthe platform, near the heel of the cutter-bar, is an adjustable butt-board, M2, the office of which is to adjust the grain to the binder, the same being adj usted according to the length of the grain, and is operated by the driver from his seat by any suitable means.

The operation of my invention is as follows: Vhen a sufficient amount of grain has accumulated on the platform outside of the springs E', the rake having assumed a position with the teeth resting outward and upward at an angle of about forty-tive degrees, the points against the curved guide-board El immediately back of the guards F2, as shown in the drawings, the rake moves in the position it is in until the rakehead strikes against the outer springs, B', which, resisting the same, cause the rake to turn partially, the teeth taking an upright position. The rake movesforward, gathering the loose straw against the springs E', but the pressure of the rake an'd grain ag inst these springs attens them to the platform, thus allowing the grain to pass over them. The rake carries the grain along the platform over the ends of the grain-holding fingers H (which rest in recesses in said platform) until the rake-head strikes said fingers on their under side and raises them. The 1ingers then catch the straw in the rear, allowing the rake to return without the straw. The springs hold the fingers in that position until the rake, returning, strikes against the inner springs, B', which turn the rake with its teeth When the rak e-head has moved the curved fingers H upward, the cords secured to said fingers are drawn taut, pulling the springs M inward, causing their short arms to bear against the bottoms of the recesses in which they are pivoted. Vhen the rake-head returns, it strikes said springs M', releasing the short arms from theirhold on the bottom, and so draws the cords back, pulling the grain-holding fingers H' down into the reful of grain may pass over it.

The weighted shoe Y, hinged to the rakehead, falls into the recess G when the rake is returned. After passing said recess G', the long side of said weighted shoe will rest on the bottom A', sliding thereon between the two recesses, holding the rake and teeth in a vertical position. After the grain has been deposited at the inner end of the i machine, the grainbinding mechanism receives it, binds it into bundles, and discharges the bundles at the side ofthe machine.

The adjustable board Ml is for the purpose ofacting against the butts of the grain to move the grain backward more or less, according to its length, in order that it may be delivered to the binding mechanism in such a position that the board will be applied centrally. The grain growing in tieldsin patches of long and short, the driver of the harvester, when reaching a change in the height of the grain, regulates this board accordingly.

Having thus fully described my invention, what I claim, and desire to secure by Letters Patent, is

1. The combination, with the grain-platform and rake-head, of the grain-holding fingers, the spring-levers,and the ropes connecting said fingers and spring-levers and passing over the rakehead, the whole arranged to operate substantially as and for the purposes herein set forth.

2. The combination of the double platform, the rake-head,mechanismfor reciprocating the rake-head, and the reversely-arranged springs secured to the bottom portion of the platform, as and for the purposes herein set fort-h.

3. The combination of the platform, the rak e-head, the mechanism for reci procating the rake-head, and a shoe hinged to the rake-head, and adapted to fall in recesses in the bottom portion ofthe platform and to slide upon said bottom, as and for the purposes herein set forth.

et. The combination, in a harvester, of a double platform, the lower platform provided with recesses and openings, as described, the reciprocating rope and spring-levers, grainholdingfingers.andreverselypointingsprings, all carried hy said lower platform, as and for the purposes herein set forth.

In testimony whereof I affix my signature, in presence ot' two witnesses, this 16th day of February, 1888.

WALLACE ADINGMAN.
